By that reasoning, nobody understands classical physics either. Aristotle's model of gravitation survived for a couple thousand years, basically uncontested. I get pretty irritated when people say nobody can or does understand quantum physics. Your intuition does no better with classical physics, or any other physics. You build an intuition through study. Almost none of us would probably even be able to discover conservation of momentum without it being laid out by someone else.
